CD8 alpha in Mouse Splenocytes. CD8a was detected in immersion fixed mouse splenocytes using 10 µg/mL Rat Anti-Mouse CD8a Monoclonal Antibody (Catalog # MAB116) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Rat IgG Secondary Antibody (red; Catalog # NL013) and counter-stained with DAPI (blue).

Background: CD8

CD8, also known as Ly-2, is a heterodimeric glycoprotein consisting of an alpha and beta chain. It is expressed on cytolytic T cells and functions in conjunction with the T cell receptor in the recognition of MHC/peptide complexes. Mouse CD8 (containing an alpha /Ly-2 or alpha ′/Lyt-2 chain) is an antigen co‑receptor on the T cell surface which interacts with MHC I molecules on antigen presenting cells (1). CD8 alpha beta heterodimer is expressed on a subpopulation of mature T cells (2, 3). CD8 alpha, without CD8 beta, has been detected on subsets of gamma δ TCR-bearing T cells (4), intestinal intrathymic lymphocytes (5, 6) and dendritic cells (7, 8).
